Changing Timer/Counter SV
There are two ways to change the SV of a timer or counter. It can be done
either by inputting a new value; or by incrementing or decrementing the cur-
rent SV. Either method can be used only in MONITOR or PROGRAM mode.
In MONITOR mode, the SV can be changed while the program is being exe-
cuted. Incrementing and decrementing the SV is possible only when the SV
has been entered as a constant.
To use either method, first display the address of the timer or counter whose
SV is to be changed, presses the down key, and then press CHG. The new
value can then be input numerically and WRITE pressed to change the SV or
EXT can be pressed followed by the up and down keys to increment and
decrement the current SV. When the SV is incremented and/or decremented,
CLR can be pressed once to change the SV to the incremented or decre-
mented value but remaining in the display that appeared when EXT was
pressed or CLR can be pressed twice to return to the original display with the
new SV.
This operation can be used to change a SV from designation as a constant to
a word address designation and vice versa.
